Mortality trends and disparities associated with aortic aneurysm and aortic dissection in the United States from 1999 to 2023: a CDC WONDER database analysis.
Article in BMC cardiovascular disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAortic aneurysm (AA) and aortic dissection (AD) are life-threatening cardiovascular diseases. AA includes thoracic (TAA) and abdominal (AAA) subtypes, while AD involves primary intimal tear. In the U.S., mortality trends, and demographic disparities remain unclear. This retrospective population-based study analyzed US AA/AD burden and disparities to guide targeted prevention and management.
methodsWe extracted AA/AD mortality data (1999–2023; urban-rural 1999–2020) for adults aged ≥ 25 in the continental U.S. from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research, stratified by sex, age, race/ethnicity and region. We calculated crude and age-adjusted rates (CMR/AAMR), and estimated annual and average annual percentage change (APC/AAPC) via joinpoint regression. Two-tailed t-tests were used (p < 0.05).
resultsBetween 1999 and 2023, there were 289,971 AA/AD-related deaths in the U.S., with AAMR declining (AAPC = -3.73%, 95% CI: -4.33 to -3.14; p < 0.001). Males and non-Hispanic Black adults had higher AAMR and slower declines. Crude mortality rose with age, while the 35–44 age group showed a small increase (AAPC = 1.04%, 95% CI: 0.63 to 1.46; p < 0.001). The Midwest exhibited a higher disease burden, and between 1999 and 2020, nonmetropolitan areas consistently showed greater disease burden compared with metropolitan regions.
conclusionsFrom 1999 to 2023, U.S. mortality from aortic aneurysm and dissection declined overall, but burdens remained disproportionately high in non-Hispanic Black individuals, those aged 85+, and the Midwest. 1999–2020 data show greater burden in nonmetropolitan areas, highlighting persistent disparities in resources and risk management.
